What Does Your Horse Actually Need From Feed & Supplements?
The shelf is built to make you feel it needs more.
Most horses on good forage need a lot less. Work out which kind of horse yours actually is before you buy anything.
Work out what’s already in the ration before adding anything.
A lot of the shelf is bought without knowing that.
Feed and supplement shelves are stocked to make every gap look urgent. A lot of it is bought by owners who haven’t worked out yet what their own horse’s diet is actually missing, if anything. This guide goes through that in order: what the ration already covers, when a balancer earns its place, when electrolytes actually apply, and how to judge the rest.
Start with what’s already in the ration
Before any supplement, the honest starting point is forage, workload, and what the horse is already eating. Most of a horse’s diet, and most of its energy, should come from forage, hay or grazing, not from a bag or a scoop. A horse on ad-lib good-quality forage, in light to moderate work, with no particular health issue, may already be getting most of what it needs. If you don’t already know roughly how much forage your horse gets in a day, that’s worth establishing before shopping for anything else. A supplement added on top of an unclear baseline is guesswork twice over.
A balancer fills a gap, it doesn’t add extra
A vitamin and mineral balancer exists to fill gaps a forage-based diet can leave, not to boost a diet that’s already complete: a concentrated source of vitamins and minerals fed in a small daily quantity, rather than a bucket feed’s worth of bulk and calories. Worth considering for a good doer on restricted forage, a horse on a forage-only diet with no hard feed, or one whose workload has increased without a matching increase in feed.
It’s less useful for a horse already getting a full fortified hard feed, since that feed is usually already balanced, a balancer on top can mean doubling up rather than filling a real gap.
Electrolytes are for real sweat, not routine
Electrolytes replace salts genuinely lost in sweat, which makes them useful after real exertion, hot-weather work, travel, or competition, not as a daily routine addition for a horse in light work. A plain salt lick or block, available at all times, covers the baseline need for most horses doing ordinary work. Electrolyte supplementation on top of that is worth reaching for around genuinely demanding exercise or heat, not by default.

Everything else needs evidence, at the labelled dose
Beyond forage, a balancer where the diet genuinely needs one, and electrolytes around real exertion, the honest position on the wider supplement shelf, joint support, calming products, hoof and coat supplements, is that value varies a great deal by product and by horse, and a general guide can’t respectably tell you a specific product will work for your specific horse.
Underdosing a product that might otherwise help is a common way to waste money on it.

The honest answer for most horses
A good doer on ad-lib forage, in light to moderate work, with no diagnosed issue, often needs a plain vitamin and mineral balancer and little else, sometimes not even that, if an existing fortified feed already covers it. The horses that genuinely benefit from more targeted supplementation are usually the ones with a specific, identified reason: a veterinary-diagnosed condition, a restricted or unusual diet, or a real, sustained increase in workload. If none of those apply, it’s entirely reasonable to conclude your horse doesn’t need anything beyond good forage and a balancer.
Forage does most of the work. A balancer fills what’s missing. Most horses need less from a feed bag than the shelf suggests, and that’s a fine thing to find out.
